Under the Sea

Why is the sea blue? What kinds of creatures live at the bottom of the ocean? How do fish survive in the freezing temperatures of the polar seas? How are oceans formed? What is the oldest living marine animal?Under the Sea is part of Discoveries, a dynamic new reference series for children. Atmospheric illustrations, strong photographs and lively text engage and encourage readers to discover for themselves the world around them. Titles from Natural History, Our World, Science and Technology and Our Past cover an exciting span of subjects: from the depths of space in Stars and Planets to the inside intricacies of machines in How Things Work. A four-page foldout in each title reveals a dramatic, and perhaps unexpected, perspective.
